How to do explosion-proof certification for explosion-proof switches? What is the basic process of explosion-proof certification?
Explosion proof limit switches, travel switches, proximity switches, etc. are common explosion-proof electrical equipment in explosive environments, coal mining industries, paint or ink manufacturers, wood processing plants, cement plants, shipping and sewage treatment. Explosion proof switches are required for all purposes. Explosion proof switches are also suitable for external electrical equipment such as motors, pumps, lighting equipment, process control devices used in hazardous manufacturers and factories, or in explosive environments that can cause flammable gases, vapors, mist gases, or flammable dust. The application scope is very wide.
Due to the presence of explosive gases or dust in such places, explosion-proof switches with explosion-proof certification must also be selected. As a product supplier, if you plan to enter such places, you must design and certify according to the requirements of GB/T 3836-2021 explosion-proof standard, and obtain the corresponding explosion-proof qualification certificate.
The basic process for applying for an explosion-proof certificate in Zhongnuo Testing is as follows:
1. Contact Zhongnuo Testing for preliminary communication on product design and explosion-proof marking requirements
2. Both parties have reached a cooperation intention
3. Zhongnuo Testing conducts technical drawing and data review and guidance, and assists enterprises in preparing enterprise preparation and explosion-proof manuals
4. Product sample testing
5. Qualified inspection, issue inspection report
6. Issue explosion-proof qualification certificate
